VA, DOD to fund up to $50 million in new research on traumatic brain injury

News Release, U.S. Department of Veteran Affairs

WASHINGTON – The U.S. Department of Veterans Affairs (VA) and the Department of Defense (DOD) launched the Long-Term Impact of Military-related Brain Injury Consortium (LIMBIC) Oct. 1, for which the two organizations pledged to fund up to $50 million, to research mild traumatic brain injuries (TBI) or concussions. 

The five-year effort will receive $25 million in funding from DOD and up to $25 million from VA, depending on the availability of funds. 

“VA and DOD share an urgent, ongoing commitment to better understand the long-term impact of TBI,” said VA Secretary Robert Wilkie. “Through this overarching effort, we are harnessing the best work of our nation’s scientists and will lay the groundwork for meaningful progress in diagnosis and treatment.” 

LIMBIC is composed of researchers and resources from more than 20 organizations, spanning VA, DOD, the National Institutes of Health, universities and nonprofit organizations. VA and DOD’s funding will support a consortium led by a team at Virginia Commonwealth University (VCU) and the Hunter Holmes McGuire VA Medical Center in Richmond, Virginia. The lead investigator, Dr. David X. Cifu, is a senior TBI specialist for VA and a professor at VCU. 

The consortium extends the work of a previous collaborative effort known as the Chronic Effects of Neurotrauma Consortium, or CENC, also led by Dr. Cifu. The existing CENC cohort, consisting of more than 2 million Veterans and service members, started in 2012 and has become the world’s largest and best-characterized research cohort dedicated to the study of military TBI. It will expand the cohort; integrate with other government, academic and nonprofit research; and spur new public-private partnerships. 

Researchers associated with CENC, and now with LIMBIC, have already documented links between combat concussions and dementia, Parkinson’s disease, chronic pain, opioid usage, and suicide risk. They have also developed specialized diagnostic tests using questionnaires, physical exams, brain imaging, fluid biomarkers, and electrophysiology to probe how the brain recovers from injury. 


The Southern Maryland Chronicle is a local, small business entrusted to provide factual, unbiased reporting to the Southern Maryland Community. While we look to local businesses for advertising, we hope to keep that cost as low as possible in order to attract even the smallest of local businesses and help them get out to the public. We must also be able to pay employees(part-time and full-time), along with equipment, and website related things. We never want to make the Chronicle a “pay-wall” style news site.

To that end, we are looking to the community to offer donations. Whether it’s a one-time donation or you set up a reoccurring monthly donation. It is all appreciated. All donations at this time will be going to furthering the Chronicle through hiring individuals that have the same goals of providing fair, and unbiased news to the community. For now, donations will be going to a business PayPal account I have set-up for the Southern Maryland Chronicle, KDC Designs. All business transactions currently occur within this PayPal account. If you have any questions regarding this you can email me at davidhiggins@southernmarylandchronicle.com

Thank you for all of your support and I hope to continue bringing Southern Maryland the best news possible for a very long time. — David M. Higgins II
